ReduxRouter does not remove hashchange-listener on unmount

When unmounting an React-app with ReactDOM.unmountComponentAtNode() the hashchange-listener of createHistory is not removed. It is added by the history.listen call in client.js, but the returned unlisten-function is not stored and never called.
Somehow the unlisten function needs to get called in ReduxRouter.componentWillUnmount().

As a quickfix, I added the unlisten-function to the returned store of historySynchronization() and called it from ReduxRouter.componentWillUnmount, but I guess thats not the best way to do it...

Thx for your help!

The issue is in client.js where history.listen is called, but the returned unlisten function is not stored. Examine ReduxRouter.componentWillUnmount to see where to call it. Look at the historySynchronization function to understand how the store and history are connected. A fix involves storing the unlisten function and ensuring it's called on unmount.
